I bought this valve about 6 years ago for my cold water tank in the loft. It replaced a plastic bodied valve which had started to drip at the connection to the HP feed pipe (plastic doesn't really cut it in extreme conditions)....it nearly caused a ceiling collapse.
Problems with this new valve started when the water flow slowed down to a dribble.
I took this valve apart and some of the (black) plastic internals had disintegrated partially blocking the flow, but fortunately the valve was still shutting off.
A valve like this should last more than a few years and the internals should not break up, the possibility of overflowing must be very high if it jams in the open position, the tank overflow will not handle anything higher than a medium flow.
A marvel of modern design

I bought this item with the intention of using it to stop water flowing over the top of my water tank. I can honestly say that this bit of kit does exactly what it purports to do. No longer do I have to worry that the roof is going to cave in on me due to water seepage.
Well done B&Q for stocking such a marvellous invention.
